Summary

Markdown is a text-to-HTML filter; it translates an easy-to-read /

easy-to-write structured text format into HTML. Markdown's text format

is most similar to that of plain text email, and supports features

such as headers, emphasis, code blocks, blockquotes, and links.

This is a fast and complete Python implementation of the Markdown

spec.
